Instance Method Details

#call(device: {}) ⇒ Object

Assembles the merged data hash. The trmnl namespace is built first, layered with static_data / cached polled data / user_data_overrides, then piped through the transform. The whole trmnl namespace is re-applied after the transform so it survives even when the transform doesn’t pass it through.
